Notes: 1. EAs is the contents of ER5, and EAd is the contents of ER6.
2. 1 is added to EAs and EAd after execution. n is the initial value of R4L or R4. When 0
is set to n, R4L or R4 is not executed.
3. Repeated twice for 2-unit retract/return, three times for 3-unit retract/return, and four
times for 4-retract/return.
4. Head address after return.
5. Start address of the program.
6. Pre-fetch address obtained by adding 2 to the PC to be retracted.
When returning from sleep mode, standby mode or watch mode, internal operation is
executed instead of read operation.
7. Head address of the interrupt process routine.
